Hastings retailer Thompson's Suits has had a similar experience, with consumers rushing through their doors to beat the cold.
Staff member Leighton McKay said winter sales were slow at the beginning of the season, but now that's no longer the case.
"Our clothing sales started off a little slow because the weather has been so warm. But since the temperatures dropped, we're getting a lot of people walk through the door and we're also getting a lot of phone calls as well.
"A lot of people are looking at our jerseys and also winter shirts, they're definitely going for the woollen side of things," he said.
"It really is amazing what's happening now that the weather has changed, we do a lot of seasonal buying, so it's really picked up more, both yesterday and today in terms of winter sales."
MetService meteorologist Melissa Oosterwijk said the cold temperatures were in no rush to make a move.
"Unfortunately it's not looking great in terms of temperature, we've got a southerly flow which is quite cold and it's not going anywhere for the next couple of days, so it's going to remain consistently cold," she said.
"Yesterday there was a lot of rain in the Hawke's Bay region, mainly in the north, it was pretty consistent around the Kaweka Ranges and in Mahia.
"Today is also looking like it will be raining and then clearing up precipitation-wise. So when it's not raining there will be fine breaks in between, there's not going to be any heavy rain," Oosterwijk said.
The region will have to withstand the southerly winds for the rest of the week before a high makes its way towards the region.
"It's moving very slowly which is why the low is remaining so consistent. The high is staying over to the west at the moment. If it was slightly further across it would be really lovely for Hawke's Bay."
